If you are having an operation and have had pethidine, or expect to get it, tell the anaesthetist so they can plan your medicines with this in mind.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
